When you think about heating a pool or spa, a common misconception is "it must be expensive to run?" Energy efficiency has improved considerably over the last few years with the use of Inverter technology. This means pool & spa heating is now much more cost-effective & environmentally friendly.

The inverter technology works by constantly measuring water temperature and adjusting the speed of the heaters compressor and fan, ensuring the most efficient setting to match heat loss. On start-up, the unit slowly ramps up compressor and fan speed based on accurate measurements of inlet water temperature, air temperature and the preset temperature.

Then as the water temperature nears your set-point temperature, the unit slows down and reduces heating capacity. In contrast, a traditional header always works at full power turning on and off based on the set temperature drawing much more power, trying to keep the water within the set temperature range. The consistent, low power draw of an inverter pool & spa heater is much more efficient and economical.

"Which inverter heater is best for me?"

There are two brands we suggest that cover most pool & spa types. Both brands are very reliable and come with great warranty and support. Read more below and contact us to discuss which would be more suitable for you!

Hayward EnergyLine Pro Inverter

The Hayward EnergyLine Pro Inverter heat pump is a high performance, energy-efficient Hayward Heat Pump that quietly and economically maintains your ideal water temperature at all times while delivering potential energy savings compared to traditional on/ off Heat Pumps and Gas Heaters. It consistently monitors the temperature and adjusts its output to supply only the required amount of energy to heat your pool or spa.

Other innovative features of the Hayward EnergyLine Inverter

• Super-quiet performance system operating at low decibels this heat pump is virtually silent from only a few metres.

• The Titanium Heat Exchanger is designed for durability and efficiency to ensure maximum heat transfer and resistance to pool chemicals.

• Designed to operate at low ambient temperatures (designed for temperatures down to -7 Degrees Celsius) you can extend your swimming time earlier in Spring and well through Autumn.

• Digital colour touchscreen interface shows real-time power consumption for immediate feedback and control.

Astral Pool Eco Inverter Heater Pump

The AstralPool range of Heat Pumps now includes both standard technology and the new Inverter technology. Inverter technology allows the swimming pool heat pump to reach an extremely high COP* compared with normal heat pumps in the market Their unique inverter technology reduces the speed of the unit as it reaches the desired temperature. This greatly saves on energy and enables you to enjoy swimming quicker and at a constant temperature.

The ECO Inverter Heat Pump range uses R32 Gas Refrigerant, which offers higher efficiency and requires less refrigerant volume per kW. This means quicker heating times and less energy used to heat up your pool. you can also expect reduced electricity consumption by approx. 10% and lower environmental impact.

Other benefits are:

• Whisper-quiet & super-efficient operation

• Faster heat-up times

• Optional WiFi Module add-on for use with the HeatPumpGo app

Get more heat for less $

Reduce your costs even further by using a pool cover. A pool cover will retain heat (approx. 7-10 degrees overnight) which means a significant reduction in the running costs.

A pool cover will also reduce evaporation by up to 98%, saving you hundreds in excess water consumption each year and keeping dirt and leaves out!

*The Coefficient Of Performance or COP of a heat pump is a ratio of useful heating, to the work required. A higher COP equates to lower operating costs.
